POCKET-OILER.

SPECIFICATION forming part of Letters Patent No. 774,328, dated November8, 1904.

Applicationflled May 5, 1904, Serial No. 206,437. (No model.) I

To all 1071 0172, it may concern:

Be it known that we, AUeUsT F. MEIssEL- BACH and WILLIAM MnrssnLnAon,Jr. citizens of the United States, and residents of 26 Prospect street,Newark, county of Essex, State of New Jersey, (whose post-office addressis also the same,) have invented certain new and useful Improvements inPocket-Oilers, fully described and .represented in the followingspecification and the accompanying drawings, forming a part of the same.

The object of the present invention is to furnish an oil-dropper whichmay be carried in safety in the pocket and which is adapted for use inoiling clocks, phonographs, sewingmachines, and similar small articleswhen repairing the same away from a workshop. The receptacle may be madecylindrical, square, or flat and is preferably made of a metallic shell,with integral bottom and a screw-socket secured upon its mouth; but theother features of the invention are independent of this particularconstruction.

The invention will be understood by reference to the annexed drawings,in which Figure 1 is a side View of the complete device, which is drawnof the natural size. Fig.

2 shows the screw-plug or stopper detached.

from the cylinder to exhibit the oil-lifter wire. Fig. 3 is an edge viewof the lower end of such wire. Fig. 4: is an enlarged View, in sectionwhere hatched, ofthe parts at the upper end of the oil-dropper. Fig. 5is a central vertical section of the blank for the threaded socket inthe first stage of its construction. Fig. 6 shows the same with themarginal flange turned downward in readiness to engage with the top ofthe cylinder. Fig. 7 shows an alternative form for the receptacle.

In Figs. 1 and t, a designates thereceptacle, made of'a brass shellhaving integral bottom and provided at the mouth or top end with anarrow flange b. A screw-socket is attached to the mouth of the cylinderby engagement with such flange, the socket being first formed from adisk of sheet metal by punching the central portion downward, as shownin Fig. 5, thus forming a cylindrical body 0, in which the thread issubsequently cut, and a marginal flange (Z, which is subse: quentlyengaged with the flange b by bending the margin of the flangedownwardly, as shown in Fig. 6, and the parts are so proportioned thatthe body 0 of the socket fits within the cylinder, as shown in Fig. 4,and the down: wardly-bent flange (Z fits just outside of the narrowflange b on the cylinder. By suitable tools the edge of the flange (Z isthen bent beneath the flange 7/, as shown in Fig. 4, which engages thesocket firmly with the receptacle [a The interior of the socket isthreaded, as shown in Fig. 4c, and a plug e is fitted to suchscrew-thread and provided with a flange f to press a packing g upon thetop of the socket. The outer side or face of the flange (Z is formedwith a groove h and the collar f with an annular ridge 6, which forcesthe packing into the groove h, and thus forms a tight joint. The packingis first fitted tightly upon the screw-thread of the plug a and is thuscarried permanently by the plug, and the forcing of the packing into thegroove 71/ prevents the packing from being pressed outwardly,which wouldloosen it from the plug and render it liable to be lost.

The plug is formed with a knob j upon its outer end for screwing it intothe socket. The plug carries the oil-lifter, which is formed of a wire71/, with the point flattened, as shown in Figs. 2 and 3, and cut toform a diamondshaped point Z. The wire is made to reach the bottom'ofthe receptacle a or cylinder (0, as indicated by the dotted lines inFig. 1, and is thus enabled to utilize the oil when reduced to thebottom of the receptacle.

The flattening of the point greatly increases the surface and theadhesion of the oil thereto when the lifter is raised from thereceptacle, and the diamond-shaped point serves to direct the oilaccurately upon any spot to which it is to. be applied.

Fig. 7 shows the receptacle of flat form with round neck of sufiicientthickness to form the screw-socket by cutting a screw-thread directly inthe neck, and the end of the neck is bent into an integral flange,having the groove h therein. In this figure the knob on the plug islettered the wire lifter 7c, and the packing g. The operation of theoil-dropper is precisely the same with this construction as with thatshown in Fig. 4.

The device is exceedingly durable in character and cheap in manufactureand is of such shape and construction as to be readily carried in thepocket without danger of leakage.

We are aware that it is common to employ a pointed wire as an oil-lifterand to secure such pointed wire to a plug of elastic material inclosedwithin a sheet-metal cap, and we do not, therefore, claim such aconstruction, but have made a specific claim to the attachment of thewire lifter directly to a solid metallic plug having a knurled head uponthe body and an annular flange or collar projected from the body tocompress a packing upon the neck of the receptacle.

Having thus set forth the nature of the invention, what is claimedherein is 1. The oil-dropper having the screw-socket at its end, thesolid metallic screw-plug e fitted to the screw-socket and having theoil-lifter wire is with diamond point secured directly in the solidmetal plug, the plug being formed with the integral knurled head 1', andthe collar f projecting outside of the knurled head and the plug, tocompress a packing upon the neck of the receptacle, as herein shown anddescribed.

2. The oil-dropper provided at the mouth with an annular seat havingtheannular groove it therein, and the screw-plug 6 having the oillifter k,the packing-washer 9 carried by the screw-plug, and the collar f uponthe plug provided with the annular ridge 2 adapted to press the packinginto the groove 7b.

3. The oil-dropper having receptacle with external flange at the mouth,a screw-socket threaded internally and having a flange larger than theflange upon the mouth of the receptacle permanently engaged therewith,to make the screw-socket a permanent attachment to the receptacle.

4. The oil-dropper having receptacle with annular circular flange 6 atthe mouth, with the screw-socket 0 having thread upon the inner sideonly, and having the flange d projected beyond the flange b and bentaround the edge of such flange beneath the same, whereby the socket maybe first threaded internally and afterward made a permanent attachmentof the receptacle.

5. The oil-dropper having a cylindrical body formed of a metallic shellwith integral bottom, and provided at the mouth with the flange [2, thescrew-socket fitted upon and engaged with such flange and having thegroove it upon its end, the screw-plug having the oil-lifter 2:, thepacking-washer g carried by the screwplug, and the collar f upon theplug provided with the annular ridge 2' adapted to press the packinginto the groove h.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
